Absorption method of gaseous organic silicon in vacuum system in organic silicon cracking reaction

The invention provides a method for absorbing gaseous organic silicon in a vacuum system in organic silicon cracking reaction, which comprises the following steps of: vacuumizing an organic silicon cracking reaction kettle by using a liquid ring vacuum pump, taking inorganic alkali liquor as a working solution in the liquid ring vacuum pump, and enabling the gaseous organic silicon entering the liquid ring vacuum pump to be in contact with the inorganic alkali liquor in the liquid ring vacuum pump in the vacuumizing process, and the gaseous organic silicon is dissolved in the inorganic alkali liquor, so that the gaseous organic silicon of the vacuum system is absorbed, and the situation that the gaseous organic silicon is condensed in the pump body to affect the work of the vacuum pump is avoided. 本申请提供一种有机硅裂解反应中真空系统气态有机硅的吸收方法，利用液环真空泵对有机硅裂解反应釜抽真空，以无机碱液为液环真空泵中的工作液，在抽真空过程中进入液环真空泵中的气态有机硅与液环真空泵内的无机碱液接触，使得气态有机硅溶解于无机碱液中，实现对真空系统气态有机硅的吸收，以此避免气态有机硅冷凝于泵体内，影响真空泵的工作。
